This will probably get moved to Tarot Spreads
When I started out, all I used was the Celtic Cross. That's changed now. I will still use it sometimes, but there are other spreads that can work better depending on the question. I like the Celtic Cross, but Destiny is right, there are a billion different versions, and that's what bothers me about it. The one I've always used and found works best for me, the first 6 cards look like this, with the 2 across the 1:
-----5-----
4--1(2)--6
-----3-----
1: Question/Querent
2: Problem
3: Subconscious Issues
4: Recent Past
5: Conscious Issues
6: Near Future
I like those meanings in those positions because they make the most sense to me. Subconscious below, Conscious above, Past behind and Future in front. The last few cards are the usual, in the line to the right:
7: Current Situation/Querent
8: Surroundings/Influences
9: Hopes/Fears
10: Outcome/Solution
But there are soooooo many different versions of this. It gets really confusing. Some have an extra card 0: Significator. I find this just confuses things for me. They also have totally different meanings for the first 4 cards, and not only that, lay them out in a completely different order. This all varies with each spread. It's frustrating!
I think the best thing for you to do is to look at a few different Celtic Cross spreads, and decide which one you feel most comfortable with, and stick with it, or a small few so you can alternate if you feel the need. This is one spread that is just never going to stop changing and confusing people, so your best bet is to look for the version you like the best and use that one. It's not important how the spreads are laid out or what the positions are, as long as you are comfortable with them and are able to use them properly. Don't forget to explore other spreads, and you can always make your own
